Be it known that we, VICTOR O; STROBEL and ARTHUR: Ho'eREBE-ycitize'ns I of the United States, and residents of Philadelphia,

Philadel hia county, Pennsylvania, have d certain new and useful Im rovements in Traveling Hoists, ofwhichft e folinvente lowing is a specification. i

V This invention relates to, traveling hoists of that ty o designed to travel-suspended overhead track-beam arranged tion will be readily understoodfro'm the following description taken in connection with the accompanying drawingsin' which "Figure 1 is a side elevationofatraveling hoist exemplifying our invention:- Fig. j2 a vertical longitudinal section Off'tlie same in the plane of lineid of Figsx l; and 3;iFi'g. 3a: sidee'levation ofthe right hand end of the a hoist,'-parts appearing injverticalsection in the plane of linefeof Figs, 2, 4 l;and;'5; Fig.4 a vertical section in the-plane of'line b of;

The electricalconnections for conveying current to thetruck motor and the hoisting motor from" the conductors 27, and the "mechanism for controlling themotors are not illustrated and may be substantially as usual in traveling hoist or crane construction.

- The'hoisting apparatus is suspended from the carriage' at such point that the load susj peuded by the hoisting rope Wlll be imposed eacltoi' the l ngbolts" and arrangeditrans j llliLlIll 'umn truck 5 which is the motordriven traction truck. As the hoisting rope falls in the vertical plane of pivot 17 and the king-bolts and the transversecenter of the 'track structure it. follows that the load will impose no twisting strains upon the carriage or track structure. and that the load is equably distributed at each side of the transverse center of thetrack structure. As the apparatus is moving along the track at cons1 erable speed the tendency of the momentum for the load would be to impose more or less severe side strains as the apparatus takes a curve ,inthe track, were it not for the fact that the hoisting apparatus is free to swing upon its pivot 17 and thus gradually but quickly accommodate the load to the new course of travel.

It is to be observed that each truck wheel is provided with a bearing at each of its sides, thus avoiding overhung wheel construction. The king-bolt connection between the trucks and the carriage permits of the apparatus freely passing any curves which the individual trucks will pass. The traction driving is done entirely at one of the trucks and the traetive power at this truck is applied at each side of the track system independently by independent truck motors the result being a peculiarly satisfactory driving of the apparatus around curves.v The disposition of the hoisting apparatus nearer the traction truck than the other truck causes most of the load to be imposed upon the traction wheels.

We claim 1. A traveling hoist comprising, a track beam, a base -member therefor extending sidewise therefrom, rails su ported by said base-member at an equal istance to each side of the beam, a pair of U-shaped truck-' bodies with their vertical members straddling the pair of rails, wheels mounted in the truck-bodiesand engaging the rails, a king-' bolt supported by each truck-body, a skeleton carriage frame disposed below the track structure and having pivotal connection with each of the king-bolts, a pivot disposed longitudinally in the carriage with its axis in the vertical plane of the axes of the king-bolts,

and a hoisting apparatus suspended from said ivot and havmg a hoisting drum disposed with its axis parallel with said pivot and so disposed that its hoisting rope will 1 fall into the common vertical plane of said dling the pair of rails, wheels mounted indeking-bolts and the axis of said pivot and the transverse center of said beam, combined substantially as set forth.

2. A traveling hoist comprising, a track beam, a base-member therefor extending sidewise therefrom, rails supported by said base-member at an equal distance to each side of the beam, a pair of U-shap'ed truckbodies with their vertical members stradpendent of each other in the truck-bodies and engaging the rails, a king-bolt supported by each truck-body, a skeleton carriage frame disposed below the track structure and having pivotal connection with each of the king-bolts, a pivot disposed longitudinally in the carriage with its axis in the vertical plane of the axes of the king-bolts, and a hoisting apparatus suspended from said pivot and having a hoisting drum disposed with its axis parallel with said pivot and so disposed that its hoisting rope will fall into the common vertical plane of said king-bolts and the axis of said pivot and the transverse center of said beam, combined substantially as set forth. i

3. A traveling hoist comprising, atraek beam, a base member therefor extendin sidewise therefrom, rails supported by saiil base-member at an equal distance to each side of the beam, a pair of U-shaped truckbodies with their vertical members straddling the pair of rails, Wheels mounted independent of each other in the truck-bodies and engaging the rails, motors carried by the opposite sides of one of the truck-bodies independent of each other and each having operative connection with one of the wheels of the truck in such manner that wheels on the opposite sides of the track-beam are independently driven, a king-bolt supported by each truclebody, a skeleton carriage frame disposed below the track structure and having pivot connection with each of the king-bolts, a pivot disposed longitudinally in the carriage with its axis in the vertical plane of the axes of the king-bolts, and a hoisting apparatus suspended.fr0m said pivot and having a hoisting drum disposed with its axis parallel with said pivot and so disposed that its hoisting rope will fall irito the common vertical plane of said king-bolts and the axis of said pivot and the transverse center of said beam, combined substantially as set forth.

4. A traveling hoist comprising, a track beam, a base member therefor extending sidewise therefrom, rails su ported by said base-member at an equal istance to each side of the beam, a pair of U-shaped truckbodies with their vertical members straddling the pair of rails, a pair of bearings carried by each vertical member of each truckbody above the rails and straddling the vertical plane of the ap n'opriate rail, wheels and so disposed that its hoisting rope will fall into the common vertical plane of said king-bolts and the axis of said pivot and the transverse center of said beam, combined substantially as se-t'forth.

5. A traveling'hoist comprising, a track beam, a base member therefor extendin sidewise therefrom, rails su ported by s'ai base-member at an equal istance tofleach side of the beam,.a pa1r of U-shaped truckbodies with their vertical members straddlin the pair of rails, wheels mounted in the tlllCi-bOdlGS and engaging the rails, motor mechanism carried y one of said truckbodies and en aging wheels thereof, a kingbolt supporte by each truck-body, a skeleton carriage frame disposed belowthe track structure and having plvotal connection with each of the kin -bolts, a pivot su ported longitudinally in t e carriage near t e king-bolt of the truck carrying said motor mechanism and havin its axis in the vertical plane of the axes o the king-bolts, and a hoisting apparatus suspended from said pivot and having a hoisting drum located near one of said king-bolts and so disposed with, its axis parallel with said pivot that the hoisting rope will fall in the common vertical planeof the king-bolts and the axis of said pivot and the transverse center of said track-beam, combined substantially as set forth.
